Broadway brawl over circus tent

Crain's New York Business: The stagehands union took to the streets near Times Square Tuesday to protest the new circus variety show, Spiegelworld's Empire New York, over its use of nonunion lighting and audio technicians. Executives at the union, Local One of the International Alliance of Theatrical Stage Employees, said they expected hundreds of members to protest all day and into the night outside a large tent that was constructed at 265 W. 45th St. to house the show. It is expected to be the union's largest demonstration in the theater district since the Broadway strike of 2007.
